very undesirable for many reasons.

v In the invention herein we have constructed? a body for use particularly in transporting and dumping wet cementitious mixtures wherein the materials 'of themixture denotsegregate to anything like the previous de'- from the body; lThe presentfinventionisdeying drawings, in which,V

Y f Y For an'un'derstanding ofthe invention reference may be had to the Vfollowing descrip- Y tion taken in connection with the accompany- Fig. l is a side elevation of a truck equipped i with a dumping body of our invention'.

The rear open end ofthe semi-circular body member 7 is embraced wit-hin a U-shaped member 1G of angle iron having ends 17 extending above the upper edges of the body to form supporting posts on which the tail gate is pivotally mounted. The tail gate comprises a substantially semi-circular plate 19 of sheet metal with a reverse channeled upper end20 and withfa substantially semi-circular reinforcing member 21 of angle iron welded to the same atits rear side. Two brackets 22 are permanently secured in spaced apart relationy to the upper end of the tail gate plate 19 at its inner side, each having an outwardly extending pin 23 to enter slots made in supporting brackets 18 permanently secured to the upwardly extending ends 17 of the U- shaped member 16. The slots in brackets 18 are open at their rear ends for the ready reception of pins 23 which are retained in said slots by pins 24 passing through the brackets 18 across the slots and back of the pins 23 after seating in said slots.

After the tail gate has been mounted on the body a rod 25, circular in cross section, is bent to snugly fit against the inner side of the body member 7 and while in such position is Welded to the plate 19. It is evident by reference to 4 that the rod bears tightly against the inner sides of the semicylindrical body member 7 and that there is an acute angle recess at the front of the rod 25 between it and the adjacent inner side of the body. This recess, indicated at 26, immediately fills with sediment when a wet mixture of concrete is placedwithin the body and the deposit of sediment together with the tight lit of the rod against the body meinber 7 provides a substantial seal against water seeping through the joint.

The body is loaded with a load of cementitious mixture such as concrete or the like when it is in horizontal position and with the tail gateV closed as shown in Fig. 5. The canvas 15 lies underneath the load.

It has been Lproven from actual practical service that with a body of the shape described the travel of a truck carr ing a load of wet mixed concrete in the body serves to keep the mixture agitated and substantially homogeneous with little or no segregation of the materials of the mixtures and with but little deposit of the finer particles of the mixture, such as in Portland cement used, as do segregate; and what does segregate settles to the bottom on the canvas 15. The cement does not adheretocanvas like it does to steel and when the body is tilted .to dump itscontents the entire contents, including all depositions of segregated finer particles of the mixture is dumped at the open rear end of the body and the mixture delivered in substantially as good condition as when it was placed in the body.

Thetransportation of a wet mixture of concrete over considerable distances has been a serious problem and one open to many defects prior to the development of the body structure disclosed herein. This body structure has proven especially practical, serviceable and effective. The'invention is defined in the appendedy claims and is to be considered comprehensive of all forms of structure coming within their scope.

We claim:

1. A truck body comprising, an elongated substantially semi-cylindrical body member` a vertical front plate closing the front end thereof and permanently secured thereto, a pivotally mounted tail gate adapted to close the rear end of the body member when in one position, and an elongated fabric strip attached at its front end to the front end plate ofthe body near its upper` end and adapted to lie within the body and against the bottom thereof, said strip being freely movable relative to the body excepting at said point of attachment.

2. A truck body comprising, an elongated body member of substantially semi-cylindrical form made from a single plate of sheet metal, a metal vertical plate at'the front end thereof permanently secured thereto to provide a front end for the body, a curved filler of sheet metal located at the front lower corner of the body and permanently secured to said front end and said body member, an elongated canvas strip at- `tached to said front end plate near its upper edge and lying within and lengthwise of the body and otherwise unconnected therewith, and a tail gate for closing the rear open end of the body.

3. In a truck body having an elongated body member of curved cross sectional form, the combination of a tailgate adapted to abut against one end thereof, and a rod of circular cross section secured to the tail gate and adapted to snugly engage the body member a distance from its end.

In testimony whereof we aiix our signatures. A
